Benjamin Scott Murphy, Greg M. Lucas, Jeffrey J. Love, Anna Kelbert, Paul A. Bedrosian, E. Joshua Rigler
2021, AGU Space Weather (19)
At present, the most reliable information for inferring storm-time ground electric fields along electrical transmission lines comes from coarsely sampled, national-scale magnetotelluric (MT) data sets, such as that provided by the EarthScope USArray program. An underlying assumption in the use of such data is that they adequately sample the spatial...

Debi Kilb, Julian J Bunn, Jessie Kate Saunders, Elizabeth S. Cochran, Sarah E. Minson, Annemarie S. Baltay, Colin T O’Rourke, Mitsuyuki Hoshiba, Yuki Kodera
2021, JGR Solid Earth (126)
The PLUM (Propagation of Local Undamped Motion) earthquake early warning (EEW) algorithm differs from typical source-based EEW algorithms as it predicts shaking directly from observed shaking without first deriving earthquake source information (e.g., magnitude and epicenter). Here, we determine optimal PLUM event detection thresholds for U.S. West Coast earthquakes using...

Biotic vs abiotic controls on temporal sensitivity of primary production to precipitation across North American drylands
Andrew J Felton, Robert K Shriver, John B. Bradford, Katharine N. Suding, Brady W Allred, Peter B. Adler
2021, New Phytologist (231) 2150-2161
Dryland net primary productivity (NPP) is sensitive to temporal variation in precipitation (PPT), but the magnitude of this ‘temporal sensitivity’ varies spatially. Hypotheses for spatial variation in temporal sensitivity have often emphasized abiotic factors, such as moisture limitation, while overlooking biotic factors, such as vegetation structure.We tested these hypotheses...
